Pollen analysis content in the atmosphere of Estepona (Málaga): year 1996

Abstract

In this work, a study about the pollen content in the Estepona (southern Spain) atmosphere was carried out during 1996. The sampling was made with the aid of a volumetric spore trap (model VPPS-2000 by Lanzoni) situated in the city centre at 14,5 m above ground level. The highest pollen concentrations were detected from March to June, period that registered almost 75% of total annual pollen; January, September and December being the months with lower pollen counts. The most important taxa, as quantities of pollen regards, were Cupressaceae, (iraca membranacea and Poaceae, followed byOleo, Quercus and Plantago. The highest peaks of pollen concentration were mainly due to the contributions of Cupressuceae and Urtica membranacea in March and Oleo and Poaceae, in June. The relationship between woody and herbaceous species pollen as well as between wild and ornamental species poll e n is more than one during all months, except March and October when the last concentrations of Cupressaceae pollen are very high.
